Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

aim of study is to evaluate esthetic and biomechanical outcome of maxillary anterior single-tooth zirconia implant supported PEKK crowns compared to lithium disilicate crowns on PEKK abutments .

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

High performance polymers may be a valid alternative to other conventional materials for abutments and crowns over zirconia implants because of their cushioning effect and elastic modulus (5.1GPa), which absorb occlusal forces and avoid overload of the underlying bone from the direct transmission of biting impacts ; which could optimize and preserve osseointegration with time. Zirconia implants with high performance polymers restorations can be considered a good alternative for replacing natural teeth.

For many years lithium disilicate has been the esthetics standard used in Veneers ,Inlays , onlays, occlusal veneers, partial crowns,minimally invasive crowns and Implant superstructures due to its natural-looking tooth colouring and excellent light-optical properties.

Due to the promising esthetics of high performance polymers as it can be veneered with different veneering materials it would successfully restore esthetics.

lithium disilicate crowns

lithium disilicate crowns are well documented in the literatures as successful restoration modality.

Group Type ACTIVE_COMPARATOR

poly ether ketone ketone

Intervention Type OTHER

Polyetherketoneketone (PEKK) forms a group of high-performance thermoplastic polymers. PEKK shows excellent biocompatibility and exhibits outstanding properties such as high wear resistance and high compressive (246 MPa), flexural (5.0GPa), and tensile strengths (115 MPa). The material is lightweight, allows shock absorption, and can be veneered with various commercially available dental materials
